Fix "ComposePanel doesn't use hardware acceleration with RenderSettings.SwingGraphics on Linux" (#1103)

Fixes https://youtrack.jetbrains.com/issue/CMP-8936

`glXChooseFBConfig` fails to find a config with `GLX_DOUBLEBUFFER,
False` on my machine, it only has double buffered configs. But
double/single buffering doesn't matter as we use pixel buffers.

Also choose a correct config that is required by
https://registry.khronos.org/OpenGL-Refpages/gl2.1/xhtml/glXCreatePbuffer.xml:
```
BadMatch is generated if config does not support rendering to pixel buffers (e.g., GLX_DRAWABLE_TYPE does not contain GLX_PBUFFER_BIT)
```

## Testing
- manually, in the clocks example
- the modified test failed before the fix, now it doesn't fail
